GEORGE BEXNS, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO JOHN J. MITCHELL, OF NEW YORK, N. Y.

FLAT-l RON HEATER.

SPECIFICATION forming part of Letters Patent No. 335,421, dated February 2, 1886.

' Application filed April 18, 1885. Serial No. 162,634. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE Barns, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Flat-Iron Heaters, of which the following is a specification.

This invention has reference to an improved flat-iron heater which can also be used advantageously as a heatingstove for warming the dshop or other place in which the heater is use In the accompanying drawings, Figure 1 represents a side elevation of my improved flat-iron-heating stove; Fig. 2, a vertical central section; Fig. 3, a horizontal section on l1ne x m, Fig. 1; Fig.4, a plan of the same; and Figs. 5, 6, and 7 are respectively a bot tom view, a side view, and an end elevation of the top stays that connect the top of the fire-pot with the jacket. Fig. Sis an enlarged detail vie of the mechanism for clamping the retaining-guides to the inner face of the fillingstrips.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the fire-pot of my improved flat-iron-heating stove, which fire-pot is made of hexagonal or other polygonal shape, according to the number of flat-irons to be heated. The fire-pot A is supported on the rim of a basket, B, which is provided with a horizontally-oscillating grate-section, O, that is centrally pivoted to a (liametrical supporting-bar, b, and oscillated by a shaker-rod, as shown clearly in Fig. 3. The rim of the basket 13 rests on a ring-shaped bottom, D, which is attached by a downwardly-extending flange, (l, to the cylindrical wall of the ash-pit E. To an exterior flange, d, of the ring-shaped bottom D is attached a cylindrical jacket, F, that is formed of as many sections as there are sides of the fire-pot, which sections are separated by slots f, and connected to the fire-pot by radial partitions f and by inclined top stays,g. The radial partitions f extend from the center of the jacket-sections to the corners of the firepot, and form, with the same, compartments for the flat-irons to be heated. The partitions f are riveted to lugs of the ring-shaped bottom and retained by recessed side lugs, g, of

the top stays, g. The vertical slots f between the jacket-sections are of such a width that the handles of the flat-irons can freely pass through the same to the outside, as shown in 5 5 Fig. 2.

The upper part of the fiat-iron-heating compartments is closed by an axially-movable top ring, F, the inner circumference of which rests on anti-friction balls of a retaining-ooh lar, F, of angular cross-section, while the outer circumference is bent downward and incloses the upper edge of the jacket F. The top ring, F, is preferably provided with half as many openings as there are compart- 6 5 ments, which openings are closed byghinged doors or gates F, that are readily opened or closed by suitable handles, 71, for conveniently V removing the flat-irons from or replacing them into the heating-compartments. The handles it serve also for shifting the top ring, F, from one compartment to the other until the mo tion is arrested by downwardly extending stop-pins, h, which are arranged near each door F and which abut against the radial partitionsf, as shown in Figs. 2 and 4.

The ring-shaped bottom D is provided with a raised convex portion, (1", inside of the flange d, said convex portion serving to support the flat-irons either in a position close to the walls of the fire-pot when they are to be heated or in an outwardly-inclined position, as shown in dotted lines in Fig. 2, when they are not required for use. The annular space of the bottom D, outside of the wall of the ash-pit, is provided with perforations 6, through which air may be drawn into the heating -compartments, said openings being opened or closed by means of a movable ring, 6, having openings registering with the openings of the bottom D. The perforated ring e is provided with a handle, 6 that extends to the outside of the jacket F and serves for moving the ring e, so as to admit air to the interior of the compartments or shut off the same. The 5 air thus drawn into the compartments is heated up and emitted through the slots of the jacket and through the openings of the top ring, F, when the flat-irons are removed or replaced. The flat-iron heater serves by this arrangement also as aheating-stove, by which the room in which the same is used is effectopening the doors F and retained by lockingplates 42 i, as shown in Figs. 2 and 3.

From the inner face of each of the fillingstrips F near the upperend thereof, projects alug, i, having an ear, 6 at its inner end, provided with a transverse perforation or eye. A locking-plate, i, fits over the ear 2", and is clamped against the shoulder i on said lugv by means of a Wedge, 2", which is inserted in said eye in the ear and driven in, all as clearly shown in Fig. 8. Near the lower end of said strips an L-shaped piece, 2' projects therefrom and extends to one side. \Vhen the hinged cover is raised, and the filling-piece F" inserted from the top, the locking-plate 1' extends across said slot and holds the strip F in place, while the L-shaped piece at the bottom assists.

The reliable connection of the jacket F with the fire-pot A is accomplished by the top stays, g, which are riveted by lugs at their outer ends to the jacket F and anchored by laterally-extending lugs g at their inner ends to downwardly-extending lugs g of the angular collar F, as shown clearly in Fig. 5, in such a manner that each lug may move vertically between the lugs on each side thereof. The

lugs g at the inner ends of the stays g support, in connection with the downwardly-extending lugs gof the collar F the upper end of the fire-pot A in such a manner as to permit the vertical expansion of the fire-pot A by the heat without interrupting or straining its connection with the j acket F,but preventing the lateral displacement or disarrangement of parts. The angular collar F is provided at its upper side with a circumferential groove for the anti-friction balls of the top ring, F, as shown in Fig. 6. On the upper rim of the collar F rests a dome-shaped cover, G, that closes the top of the fire-pot. The cover G is provided with an opening and a sliding door, G, that moves sidewise by means of a slide-ring, G fitted to the upper contracted part of the cover G.

For supplying the fuel to the upper part of the fire the door G is moved sidewise, and the fuel'dumped through the opening into the magazine M at the interior of the fire-pot. On the rim at the upper part of the cover G rests an intermediate detachable pipe-section, m, that forms the connection with the stove-pipe. The rim of the cover G, as well as the pipesection m, is recessed at diametrically-opposite points, said recesses registering with each other, so as to form the bearings for the pivots of the damper m. By detaching the intermediate pipe-section, m, the damper can be removed for cleaning, also the cover G, so

that access is given to the interior of the firepot. v

The sides of the polygonal fire-pot are reenforced by inwardly extending diamondshaped projections, which have the advantage not only to contract the throat of thefire-pot, so as toconfine the gases, but also to strengthen the same against warping and cracking. This feature of the fire-pot and the movable ventilating-ring of the bottom form part of a separate application for Letters Patent for a heating-stove, which has been filed at the same date herewith-viz., April 18, 1885, Serial No. 162,633and to which reference is made.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a polygonal fire-pot, a ring-shaped bottom surrounding said firepot and having a raised convex ring therein, an exterior cylindrical jacket having vertical slots, and a movable top ring having openings with hinged doors, substantially as de-v scribed.

2. The combination of a polygonal fire-pot, a cylindrical jacket surrounding the same and having vertical slots for the handles of flatirons, a ring-shaped bottom for said jacket, a top ring having openings with hinged doors, an angular collar resting on the top of the firepot and having downwardly-extending lugs, and top stays rigidly attached to said jacket and having lugs embracing said downwardlyextending lugs, whereby vertical expansion of the fire-pot is permitted, substantially as described.

3. The combination of a fire-pot, an exterior jacket formed of sections separated by vertical slots, a ring-shaped bottom for said jacket, a movable top ring having openings with hinged doors, and detachable filling-strips for closing said slots, substantially as described.

4.. The combination of afire-pot, an angular collar resting thereon, said collar having downwardlyextending lugs, an exterior jacket, radial partitions, and top stays within said jacket providedwith side and end lugs, said stays being secured to the jacket at one end, their side lugs supporting said partitions, and the lugs at their other ends engaging said downwardly-extending lugs of the collar, substantially as described.

5. The combination of afire-pot, an exterior 7. The fire-potA, exterior jacket, F, formed its lower end with an L-shaped piece, and I 5 of sections separated by vertical slots, the ringshaped bottom D for said jacket, and movable top ring, F, provided with hinged doors, in combination with the strips F provided with the lug 2', having shoulder i and perforated ear i the locking-plate i, and the wedge i, for clamping said locking-plate against said shoulder, as and for the purpose specified.

8. The fire-pot A, exterior jacket, F, formed of sections separated by vertical slots, the ringshaped bottom D for said jacket, and movable top ring, F, provided with hinged doors, in combination with the strips F provided near near its upper end with the lug 6, having the shoulder t" and perforated ear i", the lockingplate i, and the wedge 2', for clamping said locking-plate against said shoulder, as and for the purpose specified.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of two subscribing witnesses.

GEORGE BENNS.
